PHP Core Roundup #16

Published on by ,

Welcome back to PHP Core Roundup series! This is post #16, where we highlight and celebrate the improvements made to PHP during the month past by the PHP development team, members of the PHP Foundation, and more.

The PHP Foundation is a collective of PHP contributors, veterans, and companies that collaborate to ensure the long-term sustainability of the PHP programming language. The foundation currently supports six contributors focused on PHP's maintenance, debt reduction, and feature development. These contributors work closely with others on coding, documentation, and discussions.

Started over a year ago, the PHP Core Roundup series offers a summary of the latest developments, discussions, and news about PHP Core, contributed by both PHP Foundation members and other participants. This post is the thirteenth in the PHP Core Roundup series.

PHP 8.3 Branching Out

PHP 8.3 has reached its feature-freeze, and release managers branched out the PHP-8.3 branch on August 31.

Now that PHP 8.3 is in a separate branch, the master branch will be the development source for PHP 8.4. Bug fixes and other improvements will be cherry-picked for PHP 8.3 (and older branches) as appropriate, but new features that are made to the master branch will not be merged to the PHP 8.3 branch.

Tools that build PHP based on the Git branches will also see a new branch, and the builds from the master branch will be named “PHP 8.4” for the first time.


The PHP development team released five new versions in August 2023:

PHP 8.2.10 and PHP 8.1.23

These releases include several bug fixes and improvements, notably in areas such as CLI, Date, Core, DOM, FFI, Hash, MySQLnd, Opcache, PCNTL, SPL, and Standard.

PHP 8.2.9, PHP 8.1.22, and PHP 8.0.30

All three include security fixes: GHSA-3qrf-m4j2-pcrr and GHSA-jqcx-ccgc-xwhv.

PHP 8.2.9 and PHP 8.1.22 additionally include several bug fixes and improvements, notably in areas such as Build, CLI, Core, Curl, Date, DOM, Fileinfo, FTP, GD, Intl, MBString, Opcache, PCNTL, PDO, PDO SQLite, Phar, PHPDBG, Session, Standard, Streams, SQLite3, and XMLReader.

Recent RFCs and Mailing List Discussions

Changes and improvements to PHP are discussed, reported, and voted on by the PHP Foundation Team, the PHP development team, and contributors. Bug reports are made to the PHP issue tracker, changes are discussed in mailing lists, minor code changes are proposed as pull requests, and major changes are discussed in detail and voted on as PHP RFCs. Documentation and the website changes are also discussed and improved at their relevant Git repositories on GitHub.

Hundreds of awesome PHP contributors put their efforts into improvements to the PHP code base, documentation, and the website. Here is a summary of some changes made by the people behind PHP. Things marked with 💜 are done by the PHP Foundation team.

RFC Updates

In Voting: Support optional suffix parameter in tempnam by Athos Ribeiro

RFC proposes to add a new optional suffix parameter to the tempnam() function.

A suffix could provide even more semantic value or context for a user inspecting the generated files, and, in specific situations, could even provide more context for software processing such files. Right now, users can only add a prefix.

Merging postponed: PDO driver specific sub-classes by Danack

This RFC proposed to introduce driver-specific \PDO sub-classes so applications can granular declare the specific PDO drivers they support.

This RFC vote was completed and accepted unanimously, but due to the implementation complexity, the changes for this RFC were not finalized before the PHP 8.3.0RC1 release. Because PHP 8.3 is beyond its feature-freeze and now that the first release candidate is released, the consensus seems to be that this RFC will not be implemented in PHP 8.3 but on the next PHP version.


While PHP 8.3 has moved to the RC cycle, the documentation available on, requires updating.

Gina P. Banyard 💜 has triaged issues in the docs and marked several of them as "good first time", which are ideal easy picks if you would like to start contributing to PHP docs. You can find the full list on GitHub.

To make it easier to view the results of changes locally, Anna Filina has prepared a Docker Compose set-up. Check it out.

Merged PRs and Commits

Following are some changes that did not go through an RFC process because they are either planned, bug fixes, or progressive enhancements.
